2015 Upper Ocean hurricane season

The 2015 Upper Ocean hurricane season was a slightly below-average and relatively costly season, featuring 12 named storms, half of which became hurricanes. Lasting from April 3 with Adelen's formation through November 17 with Leo's dissipation, the season featured 3 major hurricanes, including two Category 4 storms (Blobby and Leo).
